My research is broadly focused on forest-insect dynamics across temporal and spatial scales. I am interested in the interaction between insect disturbances, climate and vegetation management; insect outbreaks and ecosystem recovery; and management strategies that maintain and/or enhance resilience. By employing inter-disciplinary applied research drawing from the fields of forestry, entomology, forest ecology, dendrochronology, and wood anatomy my goal is to underscore the forest conditions that need to be maintained in order for existing ecosystems to persist over long time frames, and adapt in the face of uncertainty.
